Patent CA-2452489-A1 (CA)
Inventor: PIROVIC ARPAD
IPC: H01J61/04
Filed: 2003-12-09
Abstract: A cathode shield for a gas discharge lamp having a predetermined size hole (32) proportional to the diameter of a cup (26) and the diameter of the glass envelope (14) of the gas discharge lamp (10). A conductive cup (26) is placed around an electrode or a filament (22). The cup (26) is covered with an insulator material (30) having a hole (32) therein. The diameter of the hole (32) in the cover has a proportional relationship to the diameter of the envelope (14) of the lamp (10) and the diameter of the cup (26). The ratio of the diameter of the envelope (14) and the hole (32) in the cover ranges between 3.5 and 4.5. The ratio of the diameter of the cup (36) and the hole (32) in the cover ranges between 2.0 and 3Ø It has been determined that these ratios improve current loads without changing discharge characteristics. Additionally, lower temperature operation and starting is facilitated with increased service life. The cathode shield is particularly applicable to germicidal lamps used in water treatment due to the cooler starting and operating temperatures required.
Patent CA-2456039-A1 (CA)
Inventor: PORTER LARRY
IPC: B01L3/00
Filed: 2002-07-30
Abstract: A collection and testing cup for fluid characterization is disclosed. The cu p has a lid assembly with a tamper evident closure; a cylinder that extends in to the fluid in the collection cup, also with a tamper evident closure; a pisto n with a conduit and one-way valve through which a portion of the fluid can be forced into an isolation chamber separate from the main collection cup for testing. The lid assembly cylinder is configured with an aperture or passage near the bottom of the cylinder to allow a small portion of fluid to enter t he lower portion of the cylinder from the collection cup chamber and a piston with a central conduit and valve initially positioned near the top of the cylinder adjacent to the lid. The piston, when pushed down the cylinder, closes the aperture communicating with collection cup chamber and forces a predetermined volume of fluid from the lower portion of the cylinder through the conduit and valve to the upper portion of the cylinder, isolating a portion of the fluid sample from the fluid in the collection cup chamber. Th e valve prevents the fluid from returning to the lower portion of the cylinder and to the collection cup chamber. A testing device may be inserted into the fluid sample at the upper portion of the piston for characterization of one or more analytes in the fluid sample.

Filed: 2002-09-23
Abstract: La présente invention concerne un procédé permettant une séparation entre qualités d'un produit agricole pendant le traitement du produit et comportant une opération consistant à définir une plage souhaitée pour une valeur de mesure. Cette valeur de mesure, qui représente une propriété du produit, définit une première qualité du produit pour laquelle la valeur de mesure se situe à l'intérieur de la plage, et une seconde qualité du produit pour laquelle la valeur de mesure est extérieure à la plage. Le procédé comporte également une opération consistant en l'analyse de la qualité du produit en cours de traitement. Pour l'analyse, on procède par prélèvement en continu d'échantillons du produit, présentation de chaque échantillon à un rayonnement électromagnétique, séparation spatiale du rayonnement électromagnétique de différentes longueurs d'ondes, et détection du rayonnement électromagnétique émis par l'échantillon. La détection produit des signaux d'intensité caractéristique du rayonnement magnétique détecté pour les différentes longueurs d'ondes. L'analyse fait également intervenir une évaluation de la valeur de l'échantillon par rapport à ladite propriété du produit à partir des signaux d'intensité, puis une évaluation d'une valeur de mesure à partir d'au moins une valeur de l'échantillon. Le procédé comporte enfin une opération par laquelle on sépare le produit de la première qualité de celui de la seconde qualité directement dans la moissonneuse-batteuse.

Title: Right angle safety needle
Inventor: BELING WILLIAM L
IPC: A61M5/00
Filed: 2002-09-30
Abstract: A right angle safety needle (32) has a base (4) to which an arm (34) is hingedly mounted at a proximal portion. The base (4) has an opening (18) at its distal portion wherethrough the vertical portion of the right angle needle (32) extends. A well (20) is formed adjacent the opening (18) and a dam (22) is provided on the side of the well (20) away from the opening (18). To retract the needle (32) from the opening (18), the horizontal portion (26) of the needle (32), which may be encased in an arm (34), is rotated about the upright (56) to which it is hingedly connected so that the needle (32) is pivoted upwards and withdrawn from the opening (18). Once the tip of the needle (32) clears the opening (18), due to the tip of the needle (32) being offset from the body of the needle (32) and the fact that the needle (32) tends to flex forward, the tip of the needle (32) is entrapped in the well (20) adjacent to the opening (18). The dam (22) forward of the well (20) provides a backstop for any further forward movement of the tip of the needle (32), thereby fixedly retaining the needle (32) within the well (20). Stops (68) are provided in the device, at its arm (34) and base (4), to prevent the needle (32) from being further moved relative to the base (4) once the tip of the needle (32) is entrapped in the well (20) of the base (4).

Title: Process for fabricating polypropylene sheet
Inventor: HINE PETER JOHN
IPC: B29C43/00
Filed: 2002-10-08
Abstract: A process for production of a monolithic article from a web of fibres of oriented polypropylene homopolymer or copolymer having a weight average molecular weight (Mw) of at least 250,000 includes the steps of subjecting the web to elevated temperature and pressure sufficient to melt a proportion of the polymer and compact it, and thereby yielding an oriented phase and a matrix phase, and effecting a heat treatment selected from (i) subjecting the compacted web to a retarded rate of cooling down to a lower temperature at or below the temperature a which the recrystallisation of the matrix is complete;  and (ii) annealing the compacted web at an annealing temperature within 15 ~C  of the temperature at which the matrix phase is completely melted. The resultant articles have good stiffness and strength, and acceptable ductility, yet corresponding articles made with polypropylene of lower Mw are brittle.

Title: Flying insects repelling system
Inventor: PUJOLAS ROBERT DAVID TROY
IPC: A01M29/18
Filed: 2004-05-12
Abstract: The system repels noxious flying insects such as mosquitos from a intended area by broadcasting a series of ultrasonic turbulence waves over the area. The turbulence waves have frequencies which are multiples of the wing beat speed of the insects. The ultrasonic waves are inaudible to humans or animals and they cause the wings of the insects to fluctuate and vibrate such that the insects avoid flying into the intended area.

Patent CA-2467862-A1 (CA)
Inventor: GALLI STEFANO
IPC: H04M3/30
Filed: 2000-09-29
Abstract: A method for determining the make-up of a subscriber loop via improved time-domain reflectometry techniques by analyzing the echo responses generated by transmittal of pulses onto the subscriber loop. In the method discontinuities along a loop are identified sequentially and in a step-by-step fashion by comparing the measured waveform to suitable waveforms generated on the basis of a hypothesized topology. Once the generated waveform that best matches the measured data has been found and a discontinuity identified, the waveform generated in correspondence of the loop topology identified so far is subtracted from the measured data to produce a compensated waveform, which, is more suitable for detection and location of the next echo.
